/**

|
* Events: (copy/paste from apple.com)
|
|
*
|
|
* webkitmouseforcewillbegin: This event occurs immediately before the mousedown event. It allows you to
|
|
* prevent the default system behavior, such as displaying a dictionary window when force clicking on a
|
|
* word, in order to perform a custom action instead. To prevent the default system behavior, call the
|
|
* preventDefault() method on the event.
|
|
* webkitmouseforcedown: This event occurs after the mousedown event, once enough force has been applied
|
|
* to register as a force click. The user receives haptic feedback representing the force click when this
|
|
* event occurs.
|
|
* webkitmouseforceup: This event occurs after a webkitmouseforcedown event, once enough force has been
|
|
* released to exit the force click operation. The user receives haptic feedback representing the exit
|
|
* from force click when this event occurs.
|
|
* webkitmouseforcechanged: This event occurs whenever a change in trackpad force is detected between the
|
|
* mousedown and mouseup events.
